NAME
    zmore - file perusal filter for crt viewing of compressed text

SYNOPSIS
    zmore [ name ...  ]

DESCRIPTION
    Zmore is a filter which allows examination of compressed or plain text
    files one screenful at a time on a soft-copy terminal. zmore works on
    files compressed with compress, pack or gzip, and also on uncompressed
    files. If a file does not exist, zmore looks for a file  of the same
    name with the addition of a .gz, .z or .Z suffix.

    Zmore normally pauses after each screenful, printing --More-- at the
    bottom of the screen. If the user then types a carriage return, one
    more line is displayed. If the user hits a space, another screenful is
    displayed. Other possibilities are enumerated later.

    Zmore looks in the file /etc/termcap to determine terminal characteris-
    tics, and to determine the default window size.  On a terminal capable
    of displaying 24 lines, the default window size is 22 lines. To use a
    pager other than the default more, set environment variable PAGER to
    the name of the desired program, such as less.

    Other sequences which may be typed when zmore pauses, and  their
    effects,  are as follows (i is an optional integer argument, defaulting
    to 1) :

    i<space>
    display i more lines, (or another screenful if no argument is
    given)

    ^D   display 11 more lines (a ``scroll''). If i is given, then the
    scroll size is set to i.

    d   same as ^D (control-D)

    iz   same as typing a space except that i, if present, becomes the
    new window size.  Note that the window size reverts back to the
    default at the end of the current file.

    is   skip i lines and print a screenful of lines

    if   skip i screenfuls and print a screenful of lines

    q or Q quit reading the current file; go on to the next (if any)

    e or q When the prompt --More--(Next file: file) is printed, this com-
    mand causes zmore to exit.

    s   When the prompt --More--(Next file: file) is printed, this com-
    mand causes zmore to skip the next file and continue.

    =   Display the current line number.

    i/expr search for the i-th occurrence of the regular expression  expr.
    If the pattern is not found, zmore goes on to the next file (if
    any). Otherwise, a screenful is displayed, starting two  lines
    before the place where  the expression was found. The user's
    erase and kill characters  may be used to edit the regular
    expression.  Erasing back past  the first column cancels the
    search command.

    in   search for the i-th occurrence of the last regular expression
    entered.

    !command
    invoke a shell with command. The character `!' in "command" is
    replaced with the previous shell command.  The sequence "\!" is
    replaced by "!".

    :q or :Q
    quit reading the current file; go on to the next (if any) (same
    as q or Q).

    .   (dot) repeat the previous command.

    The commands take effect immediately, i.e., it is not necessary to type
    a carriage return. Up to the time when the command character itself is
    given, the user may hit the line kill character to cancel the numerical
    argument being formed. In addition, the user may hit the erase charac-
    ter to redisplay the --More-- message.

    At any time when output is being sent to the terminal, the user can hit
    the quit key (normally control-\). Zmore will stop sending output, and
    will display the usual --More-- prompt. The user may then enter one of
    the above commands in the normal manner.  Unfortunately, some output is
    lost when this is done, due to the fact that any characters waiting in
    the terminal's output queue are flushed when the quit signal occurs.

    The terminal is set to noecho mode by this program so that the output
    can be continuous. What you type will thus not show on your terminal,
    except for the / and ! commands.

    If the standard output is not a teletype, then zmore acts just like
    zcat, except that a header is printed before each file.
